[PATCH v1 04/24] IB/{core,hw}: ib_pd should not have ib_uobject pointer

[Yuval Shaia <yuval.shaia@oracle.com>]

From: Shamir Rabinovitch <shamir.rabinovitch@oracle.com>

As a preparation step to shared PD, where ib_pd object will be pointed
by one or more ib_uobjects, remove ib_uobject pointer from ib_pd struct.
